"[It] was inspired by Lance, as well as his three kids," Crow says of the song. "It's kind of a reminder, particularly when you look at his young children, how they gravitate to goodness and to light . . . The idea of the song is that no matter how chaotic it is, wildflowers will still spring up in the middle of nowhere."

As the Grammy-winning singer-songwriter prepares to release her fifth studio album, she has been cheering on Armstrong, who is in the midst of his ninth Tour de France -- almost nine years after being diagnosed with the testicular cancer that eventually spread to his lungs and brain. Now a cancer survivor, the cycling superstar is moving closer to winning his seventh consecutive Tour, maintaining his lead on Wednesday as he rode from Pau to Revel. Armstrong and his ex-wife Kristin have a five-year-old son, Luke, and three-year-old twin daughters, Grace and Isabelle. The couple divorced in 2003.

Along with Wildflower, Crow's fans can also look forward to hearing a deluxe edition of her favorite songs on a fall dual-disc release of Starbucks Hear Music's Sheryl Crow's Artist Choice. The compilation will feature Crow's new acoustic versions of Aretha Franklin's "I Never Loved a Man (The Way I Loved You)," Willie Nelson's "Blue Eyes Cryin' in the Rain" and James Taylor's "You Can Close Your Eyes."
